whats the reality of the 3-5 flare?

So ive read alot about the 3-5 flare, but theres no consensus about what it really is caused by, or how to fix it. I had it with SCT canned tunes bad, but got MPD from truck source and it seems to be alot better. Is it the direct drive solenoid getting weak? Would getting a new stock solenoid help or do I need to get the ones that are basically a gogo solenoid?

you can do either solenoid... If your transmission had a issue than the solenoid will just bandaid it and give you more time- if your trans is in good shape than it can work nicely and prolong some issues.

I'm no transmission expert but on my tow tune (right after programming it) has a nasty 3-5 flare only while the trans is in its relearn process. I can always make it go away by:

1: 0-30 mph 1/4 (3-5 flare present)
2: 0-30 mph 1/4 (3-5 flare gone)
3: 0-45 mph 1/2 (3-5 flare present)
4: 0-45 mph 1/2 (3-5 flare gone)
5: 0-60 mph 3/4 (3-5 flare present)
6: 0-60 mph 3/4 (3-5 flare gone)
7: 0-75 mph WOT (3-5 flare present)
8: 0-75 mph WOT (3-5 flare gone)

After doing each run I allow the truck to slow down a few mph before stopping the truck and starting the next run.(don't hit the brakes immediately after the truck reaches the desired mph for that run) After doing this process while the trans is in a relearn it completely takes my 3-5 shift flare away. I've tried this with my extreme tunes and it cures the flare 90% of the time. Just makes sure you find a road that allows you to start and stop several times and that you just reprogrammed the truck. I would try this before changing solenoids.
